2. Craft & Performance
All drill bits of the M14-10pc Red Exposed Diamond Set adopt advanced vacuum brazing craft, the core technology that guarantees durable performance of the M14-10pc Red Exposed Diamond Set. The exposed diamond segment structure of the M14-10pc Red Exposed Diamond Set reserves more open gaps between diamond grits, accelerating debris discharge and reducing friction heat during continuous drilling. Unlike fully covered diamond drill bits, the exposed grit design of the M14-10pc Red Exposed Diamond Set avoids clogging with stone powder, maintaining consistent sharpness for long-hour construction work. The thickened high-strength steel body of the M14-10pc Red Exposed Diamond Set is coated with matte red anti-corrosion paint, resisting rust even in humid wet drilling environments. Standard M14 thread connection of the M14-10pc Red Exposed Diamond Set fits 100/115/125mm angle grinders worldwide, enabling one-set multi-scene drilling operation. The serrated tooth edge of each core bit in the M14-10pc Red Exposed Diamond Set prevents tile chipping and cracking, producing smooth clean round holes without rough edges. The firm brazing bond of the M14-10pc Red Exposed Diamond Set stops diamond grit shedding under high-speed rotation, greatly extending the service life of every drill bit in the set.
Application
The multi-size M14-10pc Red Exposed Diamond Set is an indispensable professional drilling kit for kitchen countertop fabricators, tile installers, renovation contractors and DIY stone processing hobbyists. The diamond core bits equipped in the M14-10pc Red Exposed Diamond Set are specially designed for precise hole drilling on glazed ceramic tile, vitrified porcelain, marble, granite, quartz stone, artificial stone and travertine. Workers widely use the M14-10pc Red Exposed Diamond Set to drill faucet holes, sink cutouts, pipeline openings and mounting holes on wall and floor stone slabs. The portable aluminum case matched with the M14-10pc Red Exposed Diamond Set makes it easy to carry the complete set to indoor and outdoor construction sites. Whether bathroom tile renovation, kitchen quartz countertop machining, garden hardscape stone paving or commercial store stone decoration, the M14-10pc Red Exposed Diamond Set covers all common aperture requirements, eliminating the need to purchase separate single-size drill bits one by one. The exposed diamond cutting edge of the M14-10pc Red Exposed Diamond Set also works efficiently for light dry drilling when water cooling is temporarily unavailable.
